Nickel Alloy Alloy 52 Annealed vs Alloy 52 Stress Relieved

Nickel Alloy · Alloy 52 temper comparison

Alloy 52 Annealed and Alloy 52 Stress Relieved are two conditions of the same nickel alloy grade, Alloy 52: Annealed versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Alloy 52 Stress Relieved is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 280 MPa (40.6 ksi) for Alloy 52 Annealed, about 36% more; tensile strength follows at 580 MPa (84.1 ksi) vs 520 MPa (75.4 ksi). In exchange, Alloy 52 Annealed is the more ductile: elongation 35% versus 28% for Alloy 52 Stress Relieved, and Alloy 52 Stress Relieved is harder (178 HB vs 150 HB). Alloy 52 Annealed runs hotter in service (500°C vs 450°C continuous).

Alloy 52 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Alloy 52 Stress RelievedChoose it when strength drives the design.
